I have a blogspot blog and I want to move to my own domain using wordpress. How do I go about doing this? The blog is relatively new but I'm thinking it would be better to start on my own as early as possible.

I want to know if there's an easy way to do this without much affecting my readers and my visitor count from search engines. I don't know much about technical stuff but would you recommend a general shared hosting or one that specializes on hosting wordpress blogs? is there a difference?

Thanks.
